The perfect combination of salty and sweet! A classic homemade Peanut Brittle recipe loaded with candied peanuts and caramelized flavor.


  • 1 cup Karo® Light Corn or Dark Corn Syrup
  • 1 cup sugar
  • 1/4 cup water
  • 2 tablespoons butter
  • 11/2 cups roasted, lightly salted peanuts
  • 1 teaspoon baking soda
  • optional – 2 teaspoons flaked sea salt


  1. Line a 15 X 10-inch baking sheet with parchment paper and coat lightly with nonstick spray, or alternately you can use a silicone mat. Also coat an off-set spatula with nonstick spray for easy spreading. Set aside.
  2. Combine syrup, sugar, water and butter in a heavy 3-quart saucepan over medium heat. Stir frequently, until the sugar dissolves and the mixture comes to a boil.
  3. Once boiling, continue to cook without stirring until temperature reaches 280°F on a candy thermometer.
  4. Gradually stir in peanuts, stirring until temperature reaches 300°F. Remove the pan from the heat and stir in the baking soda. Mixture will foam slightly and become lighter in color.
  5. Immediately pour the mixture onto the prepared cookie sheet. With the off-set spatula, spread the mixture evenly to edges. Sprinkle with flaked sea salt, if desired.
  6. Cool and break into pieces.
